Dozens of Doctor Who TV episodes are lost as visual film recordings, but they survive as audio soundtracks, digitally remastered with additional linking narration by members of the original cast. This handsome box set collects six adventures which are either wholly or partially lost from the TV archives, but which can be enjoyed in their entirety on audio. Presented in chronological order of transmission, the stories in this collection are The Enemy of the World; The Web of Fear; Fury from the Deep; The Wheel in Space; The Invasion; and The Space Pirates.
